Sponsor's own description
This study aims to evaluate the efficacy of two traditional Chinese medicine (TCM) formulas, Danggui Shaoyao San (DSS) and Cuscuta Chinensis (Tu Si Zi), in treating primary dysmenorrhea (PD). Primary dysmenorrhea, a common condition characterized by painful menstrual cramps, affects many women of reproductive age and significantly impacts their quality of life. Conventional treatments, such as NSAIDs and oral contraceptives, often have limited efficacy or side effects, underscoring the need for alternative therapeutic options. In this randomized, double-blind study, participants will be divided into four groups: DSS, Tu Si Zi, a combination of DSS and Tu Si Zi, and a placebo group. The study will measure treatment outcomes using the Visual Analogue Scale (VAS) for pain and the Menstrual Symptom Questionnaire (MSQ), which captures physical and emotional symptoms. Additionally, TCM-based tools like pulse diagnosis and constitution questionnaires will be employed to explore personalized treatment strategies. This research seeks to determine whether these TCM formulas can alleviate pain and improve other menstrual symptoms, potentially providing broader benefits than conventional painkillers. The findings aim to support evidence-based integration of TCM in managing dysmenorrhea and inform clinicians and patients about effective therapeutic choices.
